Detailed Description
As mentioned above, in the medical technology field, a large number of tests and experiments are required, and the tests and experiments usually need to be performed by first collecting sample specimens and then classifying the sample specimens according to the types of tests and experiments to be performed before they are tested. After the sample is collected, the collected sample needs to be packaged in time, otherwise some sample samples to be detected may not be packaged in time, so that the detection result is inaccurate. Certainly, not only the sample to be detected who gathers need encapsulate, also need in time encapsulate in some other medical supplies, for example in time encapsulate in order to prevent that the medicine from going bad because of reacting with the material in the air etc.. Therefore, the method has great significance for timely packaging the medical sample.
Currently, when a medical test sample is packaged, a medical care or a technician usually packages a sample manually. However, with the development of medical technology, the number of sample specimens for medical detection is larger and larger, and the manual packaging is inefficient. In addition, a mode is that medical personnel are combined with machinery to package a sample needing to be packaged, and the mode still needs a large amount of manual participation, wastes resources and influences packaging efficiency.
Based on the scheme, the action parameter for packaging the current medical detection sample is generated by combining the hysteresis parameter of the packaging component through a mode of detecting the position information of the sample in real time, so that the medical detection sample is packaged according to the action parameter. Therefore, the automatic packaging of the medical detection sample is realized, a large amount of human resources are not needed, and the packaging efficiency can be improved. Meanwhile, the mechanical hysteresis factor of the packaging part is fully considered, and the precision of packaging the detection sample is improved. In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a method for packaging a medical test sample, which may include the following steps:
step 101: acquiring first position information of at least one medical detection sample in real time;
step 102: determining a hysteresis parameter of at least one of the package components;
step 103: for each packaging component, determining an action parameter of the current packaging component for packaging the current medical detection sample according to the acquired first position information of the current medical detection sample and the hysteresis parameter of the current packaging component;
step 104: and carrying out packaging operation on the current medical detection sample according to the action parameters.
In the embodiment of the invention, when the medical detection sample is packaged, the position information of the medical detection sample is firstly collected in real time, and then the hysteresis parameter of a packaging component for packaging the medical detection sample is determined. Therefore, when each packaging component packages the medical detection sample, the action parameters of the current packaging component for packaging the current medical detection sample can be determined according to the position information and the hysteresis parameters of the current medical detection sample, and the packaging operation of the current medical detection sample can be realized according to the action parameters. Therefore, according to the scheme, the action parameters of the packaging component are determined according to the real-time position of the medical detection sample, the packaging operation can be realized without manually correcting the position of the medical detection sample, and the efficiency of packaging the medical detection sample can be improved. In addition, the scheme also fully considers the mechanical hysteresis characteristic, and takes the hysteresis parameter of the packaging component into the action parameter, so that each medical detection sample can be accurately packaged when the packaging component performs the packaging operation.
In addition, the embodiment of the invention can also realize multi-step packaging of the sample to be detected through different packaging components. For example, for a sample to be detected which needs to be sealed by a sealing film, the sample to be detected can be transversely wrapped by a first sealing component; then longitudinally wrapping the water sample to be detected by using a second packaging part; and finally, sealing the transversely wrapped interface and the longitudinally wrapped interface by using a third packaging component. Of course, when the sample to be detected is packaged, the number of the packaging components and the function of each packaging component can be determined according to specific situations.
In the embodiment of the present invention, it is considered that a predetermined specific position is set for placing a sample to be detected, such as a sample tube slot. Of course, the position information of the current medical test specimen may be detected by a device such as a position sensor, and the parameters of the packaging operation performed on the medical test specimen by the packaging member may be determined by using the position information.
After obtaining the position information of the medical test sample and the hysteresis parameters of the packaging components, when determining, for each packaging component, the motion parameters of the current packaging component for packaging the current medical test sample according to the acquired first position information of the current medical test sample and the hysteresis parameters of the current packaging component, as shown in fig. 2, step 103 may be implemented as follows:
step 201: determining the packaging part distance between the current medical detection sample and each packaging part according to the first position information;
for each package component:
step 202: acquiring the modulus length of the current packaging component; the module length is used for representing the distance between two adjacent operating parts mounted on one packaging component;
step 203: determining the working time and the working rotating speed of the current packaging component according to the packaging component distance, the hysteresis parameter and the modulus length corresponding to the current packaging component;
step 204: and determining the working time and the working rotating speed of the current packaging component as the action parameters corresponding to the current packaging component.
In the embodiment of the invention, when determining the action parameter of the current packaging component for packaging the current medical detection sample, the packaging component distance between the current medical detection sample and each packaging component can be determined according to the first position information, then the module length representing the distance between two adjacent operation parts mounted on each packaging component is obtained for each packaging component, and thus the time and the working speed of the current packaging component for starting working can be determined according to the packaging component distance, the hysteresis parameter of the packaging component and the module length, namely the action parameter of the current packaging component is determined.
Of course, multiple operating parts may be generally mounted for the same package component to perform the packaging operation. For example, for a circular rotating shaft of the packaging component, it is considered that three operating parts are uniformly distributed and mounted on the circular rotating shaft and are respectively mounted at the positions of 0 degrees, 120 degrees and 240 degrees, so that the operating parts mounted at different positions can be respectively used for performing the sub-packaging operation through the rotation of the rotating shaft of the packaging component. Obviously, the operation parts mounted on the same packaging component may be operation parts for executing the same operation function, or may be operation parts for executing different types of operation functions, and different packaging components may adopt different installation modes of the operation parts according to requirements.
In step 202, when the module length of the current package component is obtained, the module length of the distance between two adjacent operation parts may be determined by considering the number of package parts installed by the package device according to the requirement and the circumference of the shaft of the package component. For example, the perimeter of a certain package is 600mm, and four operating parts are installed in the device, so that the module length of the package is 150 mm. And the working time and the working rotating speed of the current packaging component can be calculated by combining the distance between the packaging components and the hysteresis parameter of the packaging components.
When determining the working time of the current packaged component in step 203, in one possible implementation, this may be achieved by:
acquiring a first conveying speed of a medical detection sample;
determining first transmission time used when the current medical detection sample is transmitted to the current packaging component according to the packaging component distance and the first transmission speed of the current packaging component;
and determining the working time of the current packaging component according to the first transmission time and the hysteresis parameter of the current packaging component.
In the embodiment of the invention, when the working time of the current packaging component is determined, the transmission speed of the medical detection sample can be firstly obtained, then the transmission time for transmitting the current medical detection sample to the packaging component is determined according to the transmission speed and the packaging component interval of the current packaging component, and the working time of the current packaging component can be determined by combining the hysteresis parameter of the current packaging component.
For example, if the distance between the current medical test sample and the current packaging component (i.e., the distance between the packaging components) is 500mm, and the transfer speed of the medical test sample is 500mm/s, it may be determined that the first transfer time for moving the medical test sample to the current packaging component is 500/500 ═ 1s, and if the lag time of the current packaging component is 0.05s, it may be determined that the current packaging component starts to operate according to the first transfer time and the lag time, so as to ensure the accuracy of packaging the current medical test sample.
When determining the operating speed of the currently packaged component in step 203, in one possible implementation, this may be achieved by:
acquiring the sample width and a second conveying speed of the current medical detection sample;
determining a second transfer time used when the current medical test sample completely passes through the current packaging part according to the width of the sample and the second transfer speed;
determining the transmission correction time used when the current medical detection sample completely passes through the current packaging component according to the second transmission time and the hysteresis parameter of the current packaging component;
and determining the working rotating speed of the current packaging component according to the modulus length and the transmission correction time of the current packaging component.
In an embodiment of the present invention, when determining the operating rotational speed of the current packaging component, the sample width and the second transfer speed of the medical test sample may be obtained first, and then the second transfer time used when the current test sample completely passes through the current packaging component may be determined according to the sample width and the second transfer speed. Furthermore, the transmission correction time when the packaging component executes the operation can be determined according to the second transmission time and the hysteresis parameter of the current packaging component, so that the working rotating speed of the current packaging component can be determined according to the transmission correction time and the modulus length of the current packaging component, and the precision of packaging the current packaging component is ensured. Meanwhile, each operation part on the packaging component can be fully utilized, so that the execution efficiency of the packaging operation is improved.
For example, if the specimen width of the current medical test specimen is 50mm, the second transport speed is 100mm/s, the second transport time is 50/100 ═ 0.5s, the hysteresis parameter of the current package is 0.05s, the transport correction time is 0.55s, and if the modulus length of the current package is 100mm, the operating speed when the operating part of the current package is moved to the next operating point should be equal to 100mm
Thereby realizingThe continuous and accurate packaging of the medical detection sample improves the packaging efficiency and precision.
When the mode of transferring the medical test sample is rotational transfer, in a possible implementation, as shown in fig. 3, the step 101 of acquiring the first position information of at least one medical test sample in real time may be implemented by the following steps:
step 301: determining a current delivery rate of the at least one medical test sample;
step 302: integrating the current transmission rotating speed to obtain the current revolution;
step 303: first position information of each medical test sample is determined according to the current revolution.
In the embodiment of the invention, when the position information of the medical detection sample is determined, the rotating speed of the medical detection sample which is rotationally transmitted is integrated, so that the rotating speed of the medical detection sample which is rotationally transmitted is integrated, the current rotating speed of the medical detection sample can be obtained in real time, and the position information of each medical detection sample can be determined according to the rotating speed of the medical detection sample. Therefore, different packaging requirements can be adopted according to the determined position information of each medical detection sample according to the requirements, and the applicability of the scheme is enhanced.
For example, if the rotation speed for rotating and transmitting the medical test sample is 0.1rpm/s, then at 2.5s, the medical test sample should be at 0.25 rpm; at 5s, the medical test sample should be at 0.5 rpm. Thus, the position information of the current medical detection sample can be determined by integrating the rotating speed in real time.
When determining the current rotational speed of the at least one medical test sample in step 301, this can be done by:
acquiring diameter historical data of a rotating shaft driving a medical detection sample to rotate and rotating speed historical data of a corresponding transmission rotating speed;
and (3) taking the diameter historical data as input and the rotating speed historical data as output to carry out neural network learning, and obtaining a formula I for calculating the transmission rotating speed as follows:
wherein n is used to characterize the transmission speed, wjThe weight corresponding to the jth sample center in the historical data used for representing the training formula I, d is used for representing the diameter of the rotating shaft, and djThe parameter is used for representing the jth sample center in the historical data, m is used for representing the number of the sample centers in the historical data, and a is a constant;
acquiring the current diameter of a rotating shaft for driving a medical detection sample to rotate;
and calculating the current transmission rotating speed corresponding to the current rotating shaft diameter through a formula I according to the current rotating shaft diameter.
In the embodiment of the invention, diameter historical data of a rotating shaft driving a medical test sample to rotate and rotating speed historical data of a rotating speed corresponding to the diameter are taken as model training data, the diameter historical data are taken as input, the rotating speed historical data are taken as output, neural learning is completed, a formula I for calculating the rotating speed is obtained, then when packaging operation is carried out, the current rotating shaft diameter of the medical test sample is obtained, and the current transmission rotating speed can be calculated through the formula I obtained through training according to the current rotating shaft diameter. Therefore, the historical data is used for training and constructing the model of the transmission rotating speed, the relevance between the diameter and the transmission rotating speed can be fully considered, the transmission rotating speed can be rapidly obtained according to the diameter, and the accuracy and the efficiency of calculation are guaranteed.
When the model is constructed, the type of the rotating shaft required to be used can be determined according to the type of the sample which is required to be subjected to medical detection frequently, so that the diameter of the rotating shaft required to be used frequently is determined, and then the historical data of the diameter and the historical data of the corresponding transmission rotating speed can be considered to be fitted by utilizing a radial basis network neural function, so that the model for calculating the transmission rotating speed is constructed.
It should be noted that the diameter of the rotating shaft mentioned above is not a diameter of a driving shaft which is a simple value, but a diameter of a circular surface formed by a medical test specimen when the medical test specimen to be transferred is placed on the driving device.
In order to ensure the packaging quality, in a possible implementation manner, as shown in fig. 4, after the current medical test sample is packaged according to the action parameters, the packaging scheme of the medical test sample provided by the present invention may further include the following steps:
step 401: controlling an ultrasonic probe to scan a packaged part of the packaged current medical detection sample to obtain an ultrasonic signal and an ultrasonic image;
step 402: analyzing and processing the ultrasonic signals to obtain a modal function;
step 403: and detecting the packaging quality of the current medical detection sample by using the modal function and the ultrasonic image.
In the embodiment of the invention, after the medical detection sample is packaged, in order to ensure the quality of the package, the quality of the package can be further detected. For example, an ultrasound probe scans a packaged portion of a packaged medical test sample to obtain an ultrasound signal and an ultrasound image, the ultrasound signal is processed to obtain a mode function, and then the effect of packaging is analyzed by combining the ultrasound image.
For example, by analyzing and processing the ultrasonic signal, the abnormal signal points generated by noise can be considered and filtered, and the image of each abnormal signal point is further specifically analyzed in the ultrasonic image, so that an accurate ultrasonic image is obtained, and thus, whether the packaging effect of the medical detection sample is not good enough can be determined according to the ultrasonic image, the conditions of insufficient sealing, wrinkles and the like occur, and a corresponding remedial measure is taken.
The analysis of the ultrasonic signal in step 402 to obtain the mode function is considered to be implemented as follows:
screening ultrasonic signals by using empirical mode decomposition to obtain at least one group of primary mode decomposition functions;
differentiating the phase information of the primary modal decomposition function aiming at each group of primary modal decomposition functions to obtain secondary modal decomposition functions; wherein the secondary modal decomposition function contains angular frequency information;
and filtering noise information components in the angular frequency information of the secondary modal decomposition function by utilizing curve fitting to obtain a modal function.
In the embodiment of the invention, when the ultrasonic signal is analyzed, the ultrasonic signal is decomposed by using an empirical mode decomposition method to obtain a primary mode decomposition function, then the phase information of each group of primary mode decomposition functions is subjected to differential processing to obtain a secondary mode decomposition function, and further, the noise information component in the angular frequency information of the secondary mode decomposition function is filtered by using a curve fitting method to obtain the mode function. By screening useful signals of the ultrasonic signals and eliminating noise signals, signal data capable of truly representing the packaging position condition of the medical detection sample is obtained. By combining the ultrasonic image, abnormal points in the image can be analyzed, so that the packaging quality can be more accurately evaluated.
For example, noise such as a spike in the angular frequency information is filtered out by phase processing and curve fitting, so as to obtain stable angular frequency information. In particular, by phase information of the mode function
By performing differential processing, corresponding angular frequency information can be obtained
Next, noise components, such as spike noise, in the angular frequency information ω are filtered out by curve fitting.
